With reference to figure 1,18 and 19, head storage device 20. will be described as shown in Figure 1 below, head storage device 20 be arranged on circuit substrate conveying device 22 above, and be arranged on the moving region that electronic-component holding apparatus 10 can move to. as Figure 18 and shown in Figure 19, head storage device 20 comprises a body element 600, and it has a plurality of single mouth portion storage area 602; A plurality of rotation head storage areas 604; With a dispensing heads storage area (not shown). single mouth portion storage area 602 comprises: a receiver hole 610, it runs through body element 600; With a stayed surface 612, it is partly cut around receiver hole 610. stayed surfaces 612, form an opening 614, described opening 614 is connected with receiver hole, pin 616 as localization part projects upwards from stayed surface 612. and a single mouth portion 54 is received by a receiver hole 610, being held part 152 supported surperficial 612 like this supports, and in two grooves 160 one of them is engaged on the pin 616. thereby, list mouth portion 54 is stored in the head storage device 20, head 54 has one jiao of position like this, this position, angle is limited by pin 616 cooperation in one of them groove in two grooves 160. and the dispensing heads storage area has the structure identical with each single mouth portion storage area 602, dispensing heads 58 are received by the receiver hole of dispensing heads storage area, make and be held the support of part 560 by the dispensing heads storage area. the stayed surface of dispensing heads storage area forms like this, guarantee by the dispensing heads 58 of support to be inhaled being inhaled of surface 566 and each single mouth portion 54 surperficial 158 mutually concordant.

Each rotation head storage area 604 comprises: a receiver hole 624, and it has circular cross-section; With a stayed surface 626, it is around receiver hole 624.Pin 628 as localization part projects upwards from stayed surface 626.Rotation head 56 is received by receiver hole 610, and the outer peripheral portion of main body 180 is supported by stayed surface 626, and groove 194 is engaged on the pin 628.Thereby rotation head 56 is stored in the head storage device 20, and head 56 has one jiao of position like this, and this position, angle is limited by the cooperation of pin 628 in groove 494.The position that stayed surface 626 forms is lower than the position that the stayed surface 612 of each single mouth portion storage area 602 forms, make by rotation head storage area 604 receive respectively rotate head 56 to be inhaled surface 200 mutually concordant with being inhaled surperficial 158,566.Head storage device 20 can be preserved polytype rotation head 56, the suction nozzle 212 of the different numbers of rotation head 56 maintenances and/or dissimilar suction nozzles 212 (as, the suction tube road has the suction nozzle 212 of different-diameter), also can preserve polytype single mouth portion 54, it keeps dissimilar suction nozzles 212.

As shown in figure 20, control device 24 mainly is made up of computer 650, and it controls X-direction mobile device 40, Y direction mobile device 42 or the like by drive circuit 652 separately.

The electronic-component mounting system of said structure, receiving circuit substrate 32, solder cream has been screen printed system and has been coated to one or more devices installation site, and the single mouth portion 54 or the rotation head 56 of installation system are installed in electronic device 154 on the circuit substrate 32.Control head holding member 52 comes holding

tube mouth portion

54,56, depends on the sum and the kind of the electronic device 154 that will install, and

ozzle

54,56 can be installed in one or more electronic devices on the circuit substrate 32 more efficiently.

At first, will describe use a single mouth portion 54 that one or more electronic devices 154 are installed in form on the circuit substrate 32.As shown in Figure 2, move to device feeding mechanism 12 or 14 by the single mouth portion 54 that ozzle holding element 52 keeps, directly over electronic device 154, stop, move down, keep electronic device 154 by suction by suction.When suction nozzle 156 kept electronic device 154, supplying negative voltage was given malleation service duct 100.After maintaining device 154, single mouth portion 54 moves up, and moves to circuit substrate 32 tops.In this motion process of head 54, the image of the electronic device 154 that is kept by suction nozzle 156 is by a picked-up in two element image picking systems 47, and the site error of the device 154 that is kept by ozzle 156 is to be determined by pattern process computer 651 according to the image that is absorbed.The site error of Que Dinging comprises the error of X-direction and Y direction thus, by the position of correcting electronic component mounting equipment 10 with mobile X-direction and Y direction, corrected X direction of principal axis and Y direction error and the X-direction of the installation site of corresponding devices on circuit substrate 32 and the error of Y direction together.The site error of determining also comprises a turning error, and it can be proofreaied and correct by rotate single mouth portion 54 around axis.Then, single mouth portion 54 is moved down into the device installation site, and electronic device 154 is installed on the circuit substrate 32.So far, stop the supply of negative pressure to malleation service duct 100, supply just is being depressed into same path 10 0, and suction nozzle 156 discharges electronic device 154 surely like this.Simultaneously, when cleaning suction nozzle 156, be supplied to malleation service duct 100 than discharging each electronic device 154 used higher malleation of malleation.

When current single mouth portion 54 replaces with rotation head 56, electronic-component holding apparatus 10 moves to head storage device 20 with mutual

exchange ozzle head

54,56. more particularly, maintenance equipment 10 moves to the single mouth of one " sky " portion storage area 602, being held under the state that part 152 remains on the position higher than the upper surface of storage area 602 of single mouth portion 54, the main body 150 of head 54 is by in the opening 614 shift-in receiver holes 610. then, the axis of head holding member 52 align with the center line of receiver hole 610 and two grooves 160 in a state that has with the same angular phasing of pin 616 under, head holding member 52 moves down. thereby, list mouth portion 54 is placed on the stayed surface 612, make and be held part 152 by pin 616 location. because bar driver part 510 keeps the angular phasing relative with opening 614, disturb the body element 600. of storage device 20 after the single mouth of placement portion 54 so can prevent driving element 510, negative pressure is stopped to the supply of negative voltage supply path 10 2, and head 54 is released thus.

After the single mouth of release portion 54, head holding member 52 moves up, and moves to the top of rotation head storage area 604.More particularly, the axis of head holding member 52 and the axial alignment of rotating head 56, in case of necessity, head holding member 52 rotates to one jiao of position, and in this position, angle, three copulational protuberances 142 do not align with three copulational protuberances 206 of first plate member.Under this state, head holding member 52 moves down.In addition, bar driver part 510 is positioned to disturb avoids the position, and in this position, driving element 510 can not disturb the body element 600 of head storage device 20.It is the angular phasing that part 217 is avoided in an interference corresponding to the main body 180 of rotation head 56 that the position is avoided in the interference of bar driver part 510.Inhale under 200 states that keep in touch of surface at suction face 130 and quilt, 52 rotations of head holding member, make in three copulational protuberances 142 each enter in three copulational protuberances 206 corresponding one and inhaled in the gap between the surface 200, and have the angular phasing identical with this copulational protuberance 206.Under this state, head holding member 52 and rotation head 56 element 52 or head 52 radially or can not be away from each other on the axial direction.So, even moving-head 56 away from the direction of head holding member 52 on to the rotation head 56 apply an external force, head 56 can not leave holding element 52 yet.In the present embodiment, copulational protuberance 142,206 is cooperated mutually, has constituted one and has left anti-locking apparatus.With inhaled surface 200 suction face that keep in touch 130 and inhaled surface 200 and cooperate and formed head negative pressure cavity 204.Under this state, negative pressure source 110 through negative voltage supply path 10 2 supplying negative voltages to negative pressure cavity 204.Thereby the rotation head is kept by head holding member 52 by suction, rotate head 56 like this and be in vertical posture, and coaxial with holding element 52.Therefore, when head holding member 52 moved vertically or rotates, rotation head 56 also moved or rotation vertically.In addition, the first malleation supply system 262 is communicated with malleation service duct 100, and malleation is supplied to rotation head 56 like this.Because the high malleation of positive pressure source 122 supplies can be kept first and second spools 280,310 current location separately.In addition, be formed on the through channel of first plate member 184, do not show, form groove 132 with negative pressure cavity and be connected, make the first negative voltage supply system 260 form groove 132 and be communicated with, so negative pressure is supplied to rotation head 56 with negative voltage supply path 10 2 via negative pressure cavity.In the present embodiment, negative voltage supply path 10 2 constitutes the part of the second negative voltage supply system; Head also plays the effect of the negative voltage supply path 10 2 of the second negative voltage supply system with negative pressure channel.Yet the through channel that this does not show also can form groove 202 upper sheds and forms at negative pressure cavity, and described through channel is formed on first plate member 184, and by this through channel, through channel 348 is connected with negative voltage supply path 10 2.In addition, can omit negative pressure cavity and form groove 202.

After maintaining rotation head 56, head holding member 52 moves up, and rotates head 56 like this and comes out from receiver hole 624.Then, head holding member 52 moves to

device feeding mechanism

12 or 14, to pick up electronic device 154 from feeding mechanism 12,14.The rotation of rotation head 56 moves to device with in 12 suction nozzles 212 each successively and draws the position, and in this position, each suction nozzle 212 applies suction to electronic device 154, thereby keeps device 154.In the present embodiment, be positioned on the rotational trajectory of each suction nozzle 212 and on Y direction the position of the device feeding mechanism 12 of the most close feed type be used as device and draw the position.

When each rotation head 56 is stored in head storage device 20, the outer peripheral portion of the main body 180 of rotation head 56 supported surperficial 626 supports. under this state, the first all spools 280 remains on their malleation supply position, so the second all spools 310 remains on their negative voltage supply position., before rotation head 56 begins to draw electronic device 154, head holding member 52 is moved upward to its final position that moves up, with with the first and second all spools 280,310 are reset to their initial position. before head holding member 52 arrives its final position that moves upward, the first all routines reset part 540 engage all first spools 280 separately first be engaged part 290, the second all routines reset part 542 engage all second fen spools 310 separately second be engaged part 320, make first and second spools 280,310 all move downward with respect to main body 180, turn back to their initial position. so far, the supply that just is being pressed onto malleation service duct 100 is stopped, thereby first and second spool 280,310 separately current locations can not be by positive press fit. therefore, first and second spools 280,810 can successfully return. in addition, one or more hinge bars 224 can also turn back to their initial position. when first and second spools 280,310 reset after, malleation is supplied to malleation service duct 100 again, make malleation can keep first and second spools 280,310 respectively main body 180 axially on current location. in the reset operation process, bar driver part 510 is positioned to disturb avoids the position, to avoid the first and second specific parts 550 that reset, 552 disturb the hinge bar 224 or first and second spools 280,310. after bar driver part 510 resets, move down to keep and when electronic device 154 was installed, bar driver part 510 also was this situation.

When rotation head 56 keeps an electronic device 154, bar driver part 510 be positioned at (a) be connected to be positioned at device draw on the suction nozzle 212 of position hinge bar 224 and (b) corresponding to above-mentioned second switching position of the valve gear 264 of suction nozzle 212.So, when head holding member 52 moves down, at first, the columniform composition surface 522 that is engaged part 240 engaging lever driver parts 510 of the part of hinge bar 224, shown in Figure 21 and 22A, then, second of second spool 310 is engaged part 320 and engages composition surface 522.When head holding member 52 further moved down, shown in Figure 22 B and 22C, hinge bar 224 pivoted, so suction nozzle 212 moves down.In addition, second spool 310 moves up with respect to main body 180, and is positioned its negative voltage supply position.Yet, because first being engaged part 290 and not engaging composition surface 522 of first spool 280, so first spool 280 is still stayed its initial position.Therefore, negative pressure is supplied to suction nozzle 212, and suction nozzle 212 can keep electronic device 154 by suction.

Each device feeding mechanism 12,14 is suitable for keeping different types of electronic device 154, even make element 154 have different one-tenth-value thickness 1/10s, promptly is of different sizes at vertical direction, and element 154 upper surface separately also has identical height and position.So when rotation head 56 kept each electronic device 154, head holding member 52 moved down a preset distance.After maintaining an electronic device 154, head holding member 52 moves up.Though second spool 310 maintains the negative voltage supply position by spool position holdout device 274, but hinge bar 224 is pivoted to its initial position by the biasing force of spring 244, suction nozzle 212 moves up like this, and electronic device 154 is picked up from device feeding mechanism 12,14.Because axially the going up of cannelure 218 present 216 of ozzle keeper 216 prolongs, so no matter ozzle 212 moves up or moves down, negative pressure can be supplied to suction nozzle 212.When rotation head 56 keeps and electronic device 154 is installed, head holding member 52 can not move to its final position that moves upward, more particularly, just move to an ad-hoc location, at this ad-hoc location, be positioned at the composition surface 522 that surface 242 is higher than bar driver part 510 a little that is engaged that is engaged part 240 of the hinge bar 224 of initial position.Thereby, prevented that bar driver part 510 from rotating with respect to rotation head 56 under the situation that is engaged surface 242 contact composition surfaces 522.This ad-hoc location of head holding member 52 is higher than above-mentioned special reset position, and it is called as the final position that moves upward of the relevant maintenance and the installation of head holding member 52.

When 56 rotations of rotation head, 12 suction nozzles 212 move to device successively and draw the position, in this position, each suction nozzle 212 keeps electronic device 154. after all suction nozzles 212 have picked up separately electronic device 154 by suction, electronic-component holding apparatus 10 moves to circuitry substrate 82 tops, and device 154 is installed on the substrate 32. in the motion process of equipment 10, one of two element image picking systems 47 absorb the image of the electronic device 154 that is kept respectively by 12 suction nozzles 212 simultaneously. according to the image of each electronic device 154 that absorbs, determine the site error of each device 154.

Because the motion of electronic-component holding apparatus 10, thereby 12 suction nozzles 212 move to the top of the corresponding devices installation site of circuit substrate 32.The turning error of each electronic device 154 that is kept by suction nozzle 212 is proofreaied and correct by rotation rotation head 56.Bar driver part 510 rotation or move to angular phasing corresponding to the suction nozzle 212 that next electronic device 154 will be installed more particularly, is rotated or is moved to suction nozzle 212 and corresponding to above-mentioned first switching position of the valve gear 264 of ozzle 212.The X-direction of the X-direction of the electronic device 154 that is kept by suction nozzle 212 and the site error of Y direction, the device 154 that causes by proofreading and correct this turning error and the site error of Y direction, and the X-direction of the corresponding devices installation site on the circuit substrate 32 and the site error of Y direction, can proofread and correct by the position that the correcting electronic device keeps equipment 10 to move.After suction nozzle 212 moved to above the device installation site, head holding member 52 moved down.Move downward in the process at holding element 52, at first, the composition surface 522 that is engaged part 240 engaging lever driver parts 510 of hinge bar 224 shown in Figure 22 D, pivots bar 224, and suction nozzle 212 moves down.At last, e shown in Figure 22 E, cannelure 218 radial grooves 468 are communicated with, and make malleation be supplied to suction nozzle 212.

Subsequently, composition surface 522 engages first of first spool 280 and is engaged surface 296,298,300,302, and first spool 280 is moved up with respect to main body 180.Figure 13 has shown an example, wherein, engages four first one of being engaged among the surperficial 296-302 by the indicated composition surface 522 of double dot dash line and is engaged surface 296.Because first spool 280 moves up with respect to main body 180, cannelure 288 leaves groove 356,358, shown in Figure 22 E, makes no longer to suction nozzle 212 supplying negative voltages.When head holding member 52 further moved down, first spool 280 moved to its malleation supply position, and in this position, cannelure 288 is communicated with groove 466,468, shown in Figure 22 F, makes supply just be depressed into suction nozzle 212.This malleation has been depressurized valve 396 and has reduced.Thereby the electronic device 154 that is placed on the circuit substrate 32 is discharged from suction nozzle 212 surely.Then, head holding member 52 moves up.In this motion process, first spool 280 maintains the malleation supply position by spool position holdout device 274, and hinge bar 224 leans on the biasing force of spring 244 to pivot, and suction nozzle 212 moves up like this.Therefore, cannelure 218 leaves radial groove 468, so, no longer to suction nozzle 212 supply malleations.Yet, because first spool 280 stops negative voltage supply to suction nozzle 212, so ozzle 212 can not apply suction to the electronic device 154 that is installed on the circuit substrate 32.

When rotation head 56 moves down when an electronic device 154 is installed, other suction nozzles 212 (with corresponding first spool 280) except the suction nozzle 212 that keeps the device 154 that the next one will install also move down with rotation head 56, shown in Figure 22 G, 22H and 22I.Yet, because other suction nozzle 212 does not align with bar driver part 510, hinged member 224 corresponding to those other ozzles 212 does not pivot, so, those other first spool 280 does not move to their malleation supply position, those other ozzle 212 can not discharge electronic device 154 separately, promptly continues to keep device 154 separately.

Four first are engaged one of them thickness according to each electronic device 154 (i.e. height) that is engaged to bar driver part 510 among the surperficial 296-302 and select. and bar driver part 510 rotates to different angular phasings, different one-tenth-value thickness 1/10s or height value corresponding to electronic device 154, make the electronic device 154 that to install thick more or high more, engage composition surface 522 to be engaged surperficial 296-302 low more. those different angular phasings all define first switching position. thereby, in the present embodiment, first spool 280 has a plurality of first switching positions, as four first switching positions. because bar driver part 510 rotates to corresponding in four angular phasings of the different-thickness value of electronic device 154 selected one, when head holding member 52 moves down, composition surface 522 in four different times corresponding one engage four first and be engaged among the surperficial 296-302 corresponding one, so make each first spool 280 in four different times corresponding one switch., no matter how many electronic device 154 different one-tenth-value thickness 1/10s are, before each device 154 contact circuit substrate 32, can stop negative voltage supply, in addition, in the time of each device 154 contact substrate 32, yet malleation is supplied to the final position that moves downward of the rotation head 56 of suction nozzle 212. when head 56 is installed electronic device 154 to be changed with device 154 one-tenth-value thickness 1/10 separately., no matter how many electronic device 154 different one-tenth-value thickness 1/10s are, each first spool 280 can not change with respect to the distance of the motion of main body 180, promptly, so be constant., composition surface 522 engages any one and first is engaged surperficial 296-302 more early, each first spool, 280 its malleation supply position of arrival is more early. therefore, changed the final position that rotation head 56 moves downward, make after each first spool 280 has arrived its malleation supply position, moving downward at once of head 56 stops. because first and second arms 226 of each hinge bar 224, there is aforementioned proportion between the length of the length of an arm and another arm in 228, so twice of the distance that the distance that suction nozzle 212 moves downward is a head holding member 52 to be moved downward., the first regular stepped difference that is engaged surperficial 296-302 is half of difference of separately thickness of two kinds of electronic devices 154 (or height) value. therefore, no matter first which is engaged among the surperficial 296-302 is chosen and engage with composition surface 522, it is simultaneous that the malleation supply position that first spool 280 switches to it is installed on the circuit substrate 32 with the electronic device 154 that is kept by suction nozzle 212.

If a suction nozzle 212 fails normally to keep electronic device 154, begin to install before the electronic device 154 that will keep thus is installed on the circuit substrate 32 at rotation head 56, device 154 is decontroled.More particularly, electronic-component holding apparatus 10 moves to the top of decontroling element collector (not shown), and bar driver part 510 moves to this suction nozzle 212 of the electronic device 154 that maintenance will be decontroled and corresponding to first switching position of the valve gear 264 of this ozzle 212.Under this state, head holding member 52 moves down, and composition surface 522 engages the hinge bar 224 and first spool 280, and suction nozzle 212 is moved down, and first spool 280 is moved upwards up to its malleation supply position.Thereby malleation is replaced negative pressure and is supplied to suction nozzle 212.In the present embodiment, first switching position that bar driver part 510 moves to is the angular phasing of driving element 520, this angular phasing corresponding to, when the electronic device 154 that will be decontroled will be installed on the circuit substrate 32 on the contrary, four of first spool 280 that engages with composition surface 522 according to preset program were engaged a corresponding surface among the surperficial 296-302.This first switching position is a specific switching position.Similarly, head holding member 52 is moved down into a position, and this position is identical according to the position that preset program is moved down into holding element 52 when the device 154 that will be decontroled is installed on the substrate 32 on the contrary.In addition, decompression cancellation parts 460 move to the decompression canceling position by a driving element (not shown), make decompression cancellation parts 460 be in its non operating state.Therefore, the malleation that is not lowered is supplied to suction nozzle 212, and electronic device 154 is released from ozzle 212 surely like this, and decontrols in decontroling the device collector.Decontrol after the electronic device 154, driving element stops to drive the cancellation parts 460 that reduce pressure, and the cancellation parts 460 that reduce pressure like this turn back to pressure and reduce the permission position, making decompression cancel parts 460 and being in its operating state.In the present embodiment, the bar driver part 510 as conventional valve switching part also plays a particular valve switching part; Integrated with the special reset components (i.e. the first and second specific parts 550,552 that reset) of bar driver part 510 one with the particular valve switching part.In addition, ozzle lowering or hoisting gear 500 also plays special valve switching device shifter; Ozzle lowering or hoisting gear whirligig 512 also plays a special valve switching device shifter whirligig.Yet, when electronic device 154 is decontroled, engage with composition surface 522 one first be engaged surperficial 296-302 and be not limited to when device 154 installations, be engaged the surface according to what preset program engaged with composition surface 522.For example,, may use four to be engaged a previously selected surface among the surperficial 296-302, previously selected surface is engaged with composition surface 522 no matter how many kinds of electronic device 154 is.In this case, the position that head holding member 52 moves downward is determined, and makes it corresponding to the previously selected surface that will engage with composition surface 522.
